Abstract

In this research, spherical sandwich Pt/Au@Pd@UIO-67@UIO-n (n = 66, 67, 69) core–shell catalysts were assembled. Au nanoparticles (NPs) were used as the core for the epitaxial growth of Pd shells, and the resulting Au@Pd core–shell NPs were successfully encapsulated at the center of monodispersed Au@Pd@UIO-67 nanospheres. Well-dispersed Pt NPs were fully fixed on their surfaces to fabricate Pt/Au@Pd@UIO-67 composites with a UIO-n coating, resulting in Pt NPs sandwiched between an inner Au@Pd@UIO-67 core and an outer UIO-n shell. The synthesized Au@Pd core–shell NPs efficiently controlled the morphology and structure of the UIO-67 and enhanced the CO selectivity of the catalyst, the Pt NPs boosted the CO2 conversion, and the UIO-n component effectively regulated the reverse water–gas shift (RWGS) reaction.
